ToA all whom 'it may concern.'

l Be it known that ll, FRANK B. Dieninsex, a citizen of the United States, residing at Elinirinin the county of Chemung and State of New York, have invented certain new and usel'ul Improvements inBelt-Guides, ot which the following is a specification.

My invention relates to nnprowmcnts in belt guides and is particularly constructed and adapted for the purpose ot' guiding the belt used in connection with -a Ford automobile tor operating the fan which draws the outside air through the radiator and forces the same over the engine cylinders.

The objects of my invention are:

First, to construct a guide of the character above indicated which can be quickly and readily applied to the standard parts of a Ford car without in any way affecting the installation or interrupting the existing arrangements of the present form of engine and its auxiliary mechanism.

Second, to construct a device of the character indicated which consists of a minimum' number of parts capable 'of being easily and cheaply manufactured and all the parts are in sight so as to enable the saine to be readily installed, inspected, adjusted or repaired.

Third, to construct a beltguide which will positively retain the belt on its cooperating pulley or pulleys, and will be enabled to spring away with the belt without oli'ering too great a resistance, thereby avoiding undue wear on the edges of the belt or impair the constant and uniform lineal speed of said belt. Fourth, other .objects and advantages of the invention and its inode of application and operation will appear from the detailed description to be hereinafter given.

The invent-ion consists of structural characteristics and relative arrangement of the several elements which will be hereinafter more fully described and particularly pointed out'in the appended claims.

ln thedrawings, in which similar reference characters indicate the same part-s throughout the several figures: y

fasher used in connection with the belt guide, and

Fig'. l is a side view of a modified form of Referring to Figs. 1, and 3,10 represents the usual Ford engine on its base plate 11. 12 is the vshaft of the engine carrying the lower fan belt pulley 13, while 1st is the upper fan belt pulley supported froni an adjustable bracket 15, secured to the engine frame, and which is connected with and rotates the fan 10. The timer controlling the ignition of the cylinders of the engine is represented by 17, and a bolt 18 is provided for securing the cover o1" the timer 17 to its casing. The constructions so far referred to are the standard parts of a Ford engine and form no part of the present invention.

The improved belt guide '19 comprising my invention, is preferably formed of round spring steel wire b: ,t into lil-shape, as shown having an eye 2U termed ai. one end which is adapted to snugly rlit armndthe bolt 1S, as clearly shown in Figs. 1 and 2. 'Ine two fingers 2l and 21 of the belt guide 19 are bent over at their free ends at right angles and backward parallel to the fingers 19, as shown in Fig. 2, to form guideways or channels 22, 22, to receive and guide the belt 16, and keep. the same from having abnormal movement along the length ofthe shaft 12, and run oft' the pulley 13 or 14. To prevent the fingers 21 and 21 of the belt guide 19 from spreading or disturbing. their proper coperative relation with eaclnother and the belt 16, there is provided a Washer 23, as shown in Fig. 3, which is punched out from sheet metal with ears 24, 24, an opening 25, and extension 2G. This washer 23, as shown in Fig. 3 is adjusted and arranged so that the two ears 24, 24, embrace or abut against the outer edges of the fingers 21, 21 nent to eye 20, and the bolt 18 is passed through the eye 20 and openingy 2 5, after the belt 16 has been properly adjusted and disposed in the channels or guides 22, 22 at the .free ends of the fingers 21, 21, as previously explained. When the belt guide 19 and its washer 23 are positioned on the bolt 18, as shown in Figs. 1 and 2, the bolt 18 is screwed into the cover of the timer 17 to firmly clamp and rigidly hold the reduced end or eye 2O of the belt guide 19 to the timer casing l?, und its `guide or channel ends 2Q in proper relation to the belt i6. rllie extension :2G on washer 23 is turned up against the side oi the bolt liezid 27, as shown in Figs. l Iund 2, tliereb f acting:y as a lock und prevents the belt guide 15) from 'Working loose from @its fastened end or eye Section 20, and preserve its proper relation with the belt 16. it will also be seen that the two wings or lugs 24, 24- by embracing the two fingers 2l, 2l .prevent said lingers from spreading. und hence cause their elinnnel or uide ends 22, 22 to frictionelly engage the ielt 16, thus the washer not only performs tlie function of u ineens to prevent n distortion of :1 section of the belt guide, but et the seme time acts as a lock to avoid displacement of the adjusted position of the belt guide.

ln the modified form shown in Fig. 4, the construction of the belt guide 19" is substantially the sinne es that shown in Figs. l and 2, except the eye 20 is formed by crossingr the singlepiece of wire, and the lingers 2l', 2l', and channels or guide ends 22. 22', being' of the seme construction. und operating in the suine manner as disclosed with references to the forni shown in Fig. l. ln v the modification of the invention illustrated in Fig. 4, no washer 23 is employed, if so desired, 'as the lingers 2l, 2l normally tend .toreturn to their set position.

)Troni the foregoing description yof the construction and relation of the parts of the invention, it will be readily seen that Iil 4the 'obje-cte end advantages 'recited in the stetement of invention are fully and elciently carried out and the resiliency of the lepring wire construction of the belt guide, when seidy guide comes in Contact with the belt, permits seid cuide to compensate or spring away with tliebelt without ctering; injurious resistancethereto and cause the eelt to weer ron its edges. The belt guide- Czin also be quickly adjusted so as to always inog'ierly guide the belt nd maintain the beit on the driving pulley i8, secured to the engii'ie slntft i2.

lvrlnit i claim is: il beit guide consisting oit e single wire sti-end lient to torni. en eye et one end and two separated iingers extending from seid eye, each of seid lingers having a channel section formed et its end adapted to receive and guide e belt.

:2. A belt guide consisting oit single wire strand lient to forni :in eye at one end and two seperated resilient fingers entending 'trom said e fe, eecli of said lingers having `formed nl end :t channel constructed and arranged to receive mid guide u. belt.

3. A belt guide consisting of' e single wire strand lient to form an eye et one end und two seperate-d resilient fingers extending from seid eye.y ezicli oi' said lingers having formed at its end channel constructed und inrzinged to receive und rguide e belt, und n washer having un opening registering with the seid eye and eers engaging the outer sides ot' the resilient fingers adjacent to seid eye troni spreading troni ciieli other.
